I've already looked around a bit and found only unrelated stuff.
My setup is a i7 2600k, 8gb ram, 250 gb SSD, 3* 500gb HD.
I first started installing on my SSD, but after 1.5 hours and 5% I stopped the installation and tried restarting it on my other drives. I first tried to drives named a: and b:, but those didn't work because blizzard apparently blocks the use of those. I tried my third HD (7 year old piece of junk) and I've gotten to 40% in 20 minutes.
Anybody know why a SSD with 500mb/s read and write is slower than an old HD? Or why A: and B: can't be used? The SSD works fine the rest of the time.
